Осуществите превращения:
C->Al4C3->CH4->CO2->CaCO3->Ca(HCO3)2:>CO2->CO
Укажите условия протекания реакций

kedr57 4Al + 3C =t=> Al4C3
Al4C3 +12HOH = 4Al(OH)3↓+3CH4↑
CH4 + 2O2 = CO2↑ + H2O
CO2 + Ca(OH)2 = CaCO3↓+H2O
CaCO3 + H2CO3 = Ca(HCO3)2
Ca(HCO3)2 + H2SO4 = CaSO4 + 2H2O + 2CO2↑
CO2 + C =t=> 2CO

4Al+3C(t°)⇒Al4C3
Al4C3+12H2O⇒4Al(OH)3+3CH4
CH4+2O2=CO2+2H2O
Ca(OH)2+CO2=CaCO3+H2O
CaCO3+H2O+CO2⇒Ca(HCO3)2
Ca(HCO3)2+2HCl=CaCl2+H2O+CO2
CO2+C(t°)=2CO
